• Calibration
During tube running measure Vdc between TP1 and GND (ground) , then adjust RV1 to have Vdc at
TP3 = 55% of Vdc at TP1.
Repeat same operation with TP2, RV2 and TP4.
Typical values of running voltages at TP1 and TP2 for IAE tube XM12 are :
IAE
VTP1
1.2 V
VTP2
2.5 V
Factory calibration voltages at TP1, TP2, TP3, TP4 can be found in the tube calibration report.
V(TP3) = 0.55xV(TP1)
V (TP4) = 0.55 x V (TP2)
